摘要
自 20 世纪 70 年代以来,人们已知任何 2、4 或 6 维的开连通流形,只要其切丛允许复线性结构,就允许复解析结构。半个世纪以来,人们一直猜想这对任何维度的流形都成立。在本文中,我们将该结果推广至 8 维和 10 维流形。该证明通过应用 Gromov 的 h-原理,将 Haefliger 最初用于研究叶状结构的方法调整至全纯情形。对于 12 维及以上的情形,该猜想仍然悬而未决。

备注
This paper has been withdrawn, due to a mistake in the proof of theorem 2.1 which then invalidates the proof of theorem 1.4. Theorem 1.5 is independent from theorem 1.4 and deemed to be correct. A new preprint containing only Theorem 1.5 (and its consequences) will appear at a later time
